Abstract

OBJECTIVES

The purpose of this in vitro study was to evaluate the effect of multiple consecutive adhesive coatings of a one-step self-etch adhesive on microleakage of Class V cavities.

METHODS

Standardized box shaped Class V cavities were prepared onto the buccal side of forty five non-carious human premolar teeth. The teeth were randomly divided into three groups of fifteen teeth in each and restored as: Group I- one-step self-etch adhesive resin (Clearfil S3, Kuraray Co. Ltd., Osaka, Japan) was applied according to the manufacturer's instructions, Group II- two consecutive same one-step self-etch adhesive application was performed, and Group III- three consecutive same one-step self-etch adhesive application was performed. After the adhesive applications light curing unit was activated for 20 seconds and the cavities were restored with a composite resin. The restorations were finished with aluminum oxide discs and the specimens were stored in water at room temperature for 24 hours before they were immersed in 2% methylene blue for 48 hours. The dye penetration was examined under a stereomicroscope and the asymtotic significance were analysed with Kruskall Wallis and Mann Whitney U tests and dentin-enamel margins were compared with each other with Wilcoxon Signed Rank test.

RESULTS

The microleakage at the dentinal margins of Class V cavities were significantly decreased with two (Group II) and three (Group III) consecutive adhesive applications (P<.05). There was no significant difference between Group I, Group II and Group III at the enamel margins (P<.05). The microleakage at the dentinal margins were significantly higher than the enamel margins in Group I and Group II but in Group III there was no statistically significant difference (P<.05).

CONCLUSIONS

Within the limitations of this in vitro study, it may be concluded that three consecutive applications of the one-step self-etch adhesive resin provided better sealing than the one coat of adhesive resin at the dentinal margins of Class V cavities.

摘要

目的

本体外研究旨在评估一步法自酸蚀粘接剂多次连续粘接涂层对Ⅴ类洞微渗漏的影响。

方法

在45颗无龋的人前磨牙颊侧制备标准化的盒状Ⅴ类洞。将牙齿随机分为三组，每组15颗，修复方式如下：第一组，按照制造商说明应用一步法自酸蚀粘接树脂（Clearfil S3，日本大阪可乐丽株式会社）；第二组，连续两次应用相同的一步法自酸蚀粘接剂；第三组，连续三次应用相同的一步法自酸蚀粘接剂。粘接剂应用后，用光固化灯照射20秒，然后用复合树脂修复窝洞。用氧化铝盘修整修复体，将标本在室温水中储存24小时，然后浸入2%亚甲蓝中48小时。在体视显微镜下检查染料渗透情况，用Kruskal Wallis和Mann Whitney U检验分析差异显著性，并用Wilcoxon符号秩检验比较牙本质-釉质边缘。
